LOCOMOTIVE ROD MECHANISM.
Application filed May 2, 1925, Serial No. 27,432. Renewed January 26, 1928.
The invention relates to locomotive rod mechanism and its nature, objects and advan tages will be best understood from the following:
It has been heretofore contemplated in this art to provide an arrangement of the main or connecting rod and the rearward coupling rods, in which the main and the rearward coupling rods lie in the same vertical plane with a push and pull connection therebetween to distribute the stresses, while the forward coupling rods lie inside the plane of the main rod. An example of such construction is to be found in my Patent No.
1,253,451 issued January 15, 1918. In this construction, however, the parts have been detachably connected by special fastening means provided for this purpose so that the parts could be separately handled, as this has heretofore been regarded as essential from a practical standpoint. This involves increase inv reciprocating and rotating weights and the arrangement also has the objection that the parts are liable to work loose under the piston thrusts. It was also diificult to secure and maintain accurate spacing of the centers.
In accordance with my invention, the mam rod of the arrangement is made multipart,
such arts, although articulated,.being connected in such manner that the parts constitute an operative unit, applied and removed as such. By this, I am enabled to cut down rotating weights, to avoid any connections liable to work loose, to always ensure proper spacing of centers, and to obtain aper fectly practical structure which secures better distribution of the thrusts.
' How these and other objects are secured, 1s
40 illustrated in preferred form in the accompanying drawin wherein 7 Fig. 1 is a si e elevation of the drivers of a locomotive equipped with my improvments, four sets of drlvers being shown for illustrative purposes only; Fig. 2 is a plan view of of Fig. 1;
Fig. 3 is an enlarged sectional view illustrating details of construction; and
Figs. 4 and 5 are respectively a top plan the arrangement and end elevation of a bushing employed In carrying out the invention. 7
Referrin to the drawings, the main crank pin is carried b an intermediate driver, say, for examp e, 1%. 3 driver.
ent showing it is composed of the member 13 and the member 14, since there is only one set of drivers to the rear of the wheels carrying the main crank pins.
The rear end of the member 13 is forked, as at 15, the fork being apertured. The eye 16 of the member 14 is shaped to fitbetween the fork for rocking to provide for the lateral flexibility required durin curvin The parts are secured toget er as to lows:
A bushing 17, see Fi s. 3 to 5, is pressed into the fork 15, witht e eye 16, of course, in place. The bushing may also be keyed, as by the key 18. Pressed into the eye is a bushing 19 which may also be similarly keyed. Between the bushing 17, (which is of a hard metal to withstand the thrusts), and the pin 7 is a rotating or floati sleeve 20, made of a suitable bearing meta This fastening arrangement unites the members 13 and 14 into a unit, and the unit is applied or removed as such; and I *havefound that the construction, besides having the advantages hereinbefore mentioned, is practical, notwithstanding its unitary character.
The sleeve 19 is relatively narrow and fits sufliciently loosely on the bushing 17 to revent pinching or binding when fiexureof tlie rod occurs under service conditions.
The wear on the bushing 19 is negligible for all practical purposes. When the bearing sleeve 20 wears and is replaced, on account of the unitary structure of the rod, the
arts are brought to true center when the ushing 17 is replaced.
It Wlll be noted that the parts are internally lubricated by the grooves indicated in the drawings.
I claim:
1.,A multi-part driving rodfor locomotive driving wheels having adjacent parts articulated together asanoperative umt for unitary application to and removable from a driving wheel pin.
2. In a locomotive having more than two sets of drivers, the combination of a multiart main rod having adjacent parts articuated together as a detachable operative unit,
